So who do you guys think killed Tyrone's girlfriend? I think it's Carol or his sister. As for who is feeding the walkers I have no idea. At first I thought it was the little girl but I think it's most likely someone else who has access to the first fence.

I have two theories.

The first one is the little girl as you mentioned. There are subtle hints that she is the one feeding the rats. She named a walker Nick, and it seems this is the same walker that was fed. She was later upset that they killed Nick, and her sister said "she's not weak, she's messed up". As for killing Karen, it probably was someone else.

My second theory is Bob Stookey, the army medic. In episode 1, he was fully awake at night and seemed to be troubled. Maybe he was hired to do an inside job on the prison and felt guilt for doing so. He also has motive to kill Karen since he was with the others when they found out about the virus.
